The package provides an SVG parser, which is currently limited to paths.
The example given below can be ran using the following command:
cargo run --example path
extern crate svg;
use svg::{Event, Tag};
use svg::path::{Command, Data};
fn main() {
let file = svg::open("tests/fixtures/benton.svg").unwrap();
for event in file.parse() {
match event {
Event::Tag(Tag::Path(_, attributes)) => {
let data = attributes.get("d").unwrap();
let data = Data::parse(data).unwrap();
draw(data);
},
_ => {
println!("Not sure how to react.");
},
}
}
}
fn draw(data: Data) {
for command in data.iter() {
match *command {
Command::MoveTo(_, ref parameters) => {
println!("Move to {:?}.", parameters);
},
Command::LineTo(_, ref parameters) => {
println!("Line to {:?}.", parameters);
},
Command::CurveTo(_, ref parameters) => {
println!("Curve to {:?}.", parameters);
},
Command::SmoothCurveTo(_, ref parameters) => {
println!("Smooth curve to {:?}.", parameters);
},
Command::ClosePath => {
println!("Close the path.");
},
_ => {
println!("Not sure what to do.");
}
}
}
}
